C ++; Eclipse linker error
So while working on how my Eclipse IDE will work, I can develop my arduino uno in eclipse. My C ++ is weak, so this is probably a nube bug on my part.
I have a blink program that is looking for the arduino library which I have compiled from the arduino IDE library. My code is pointing to the header file and my code is finding it ok; what can I push to:
#include <arduino.h>
and go to header view
this: "C: /programs/arduino-1.0/hardware/arduino/cores/328p_lib/libuno_library.a" is a valid path ... but I get the following error:
>****** Build of configuration Debug for project project1 ****

Ok after spending 2 days or so fun time I finally found the problem.

When adding a static library to the linker, you need to remove the lib prefix and the .a suffix. not sure what that means.

Right click on the project> Click on C / C ++ BUild> Preferences> GCC C ++ Linker> Libraries
Click the first Add icon> Add Library Name (no .a suffix, suffix will be added automatically)
This will ensure that the library is added to the project.
If the library is part of another project> Go to GCC C Compiler> directory> Add directory
This will ensure that there is a library to get the compilation.
